1N3643 - 1N3647, 1N4254 - 1N4257
and 1N5181 - 1N5184
Voidless Hermetically Sealed
High Voltage Rectifier
Qualified per MIL-PRF-19500/279
DESCRIPTION
These “standard recovery” high voltage rectifier diode series are military qualified to MIL-PRF-
19500/279 for the 1N3644 through 1N3647 part numbers. They are ideal for high voltage,
high-reliability applications where a failure cannot be tolerated. These 0.10 and 0.25 Amp
rated rectifiers with working peak reverse voltages from 1000 to 10,000 volts are hermetically
sealed with voidless-glass construction.
Available on
commercial
versions
